What are your recommendations for improving my child's condition? Is a medical consultation necessary at this stage?

If your child has been experiencing a runny nose for 7 days and woke up with ear pain, it may be related to the cold and sinus congestion. Giving them a pain reliever like Advil can help in the meantime. Keep an eye on their symptoms and if the ear pain persists or worsens for more than 3 days, it's a good idea to consult a doctor for further evaluation. Encouraging them to drink plenty of fluids and using a gentle sinus rinse can also help alleviate the symptoms.
